Iq to Phase Conversion Method and Apparatus

3. The method of claim 2, wherein the predetermined scaling factor is 20.

4. The method of claim 2, wherein converting the first absolute value into the first logarithmic value further comprises: providing the first logarithmic value by taking a nearest integer of the scaled logarithmic domain first value as the first logarithmic value.

6. The method of claim 5, wherein converting the second absolute value into the second logarithmic value further comprises: providing the second logarithmic value by taking a nearest integer of the scaled logarithmic domain second value as the second logarithmic value.

9. The method of claim 1, wherein the providing the subtract value further comprises: adding into a subtract value of subtracting the first logarithmic value from the second logarithmic value a predetermined offset such that the added subtract value is a positive integer.

17. The apparatus of claim 15, further comprising a logarithmic storage unit configured to store multiple logarithmic values each is corresponding to a respective logarithmic index value, and wherein the first conversion module and the second conversion module are implemented by the logarithmic storage unit which provides the first logarithmic signal by selecting a logarithmic value taking the first absolute value as the logarithmic index value, and provides the second logarithmic signal by selecting a logarithmic value taking the second absolute value as the logarithmic index value.
